I'm working on my thesis project on financial mathematics. One problem I'm having is that I want to find out if there is some correlation between a theoretical curve and scatter point data.

Here is the scatter data and the theoretical curve that I have.

Is there some easy way of doing this?

detrend the data using your theoretical curve then perform a t-test to determine the likelihood that the data is centered around zero, is what i would do.
